Outdoor air (ODA):
Install the fresh air intake (wall or roof) at a sufficient distance from any are
high pollution (trees, exhaust fumes, road, etc).
This duct must be sealed and insulated to prevent condensation.
Supply air (SUP):
To avoid thermal losses and optimize the performance of the installation, it
is recommended to use insulated ducts.
Extract air (ETA):
To avoid thermal losses and optimize the performance of the installation, it
is recommended to use insulated ducts.
Exhaust air (EHA):
This duct must be sealed and insulated to prevent condensation.
By-pass:
The IDEO has a 100% heat exchanger bypass system which allows free
cooling by night. The principle of free-cooling uses free energy from the
outdoor air to ventilate and cool buildings when outdoor air temperature is
lower than the exhaust air temperature.
